However, there was this very cool video, shot from a balcony on a building just a few blocks up from us, showing the amazing stuff the lake was doing when the air temperature was 50 degrees or so colder than the water temperature (from WGN's Tom Skilling's post on FB).
I actually went out on the first day of the sub-zero cold, having a Dr.'s appointment, and various other errands that I tacked onto that, but it was only heading for sub-zero when I was outside, although the last block (coming back in from the fifth bus ride) was pretty brutal, as it was maybe -1°, but with a raging wind coming up Sheridan Rd. ... froze my face up real good.
